What to do when the material suction machine does not suck or has insufficient suction?

The material suction machine is standard auxiliary machine for enterprises that produce injection molded products such as extruders and injection molding machines. It uses vacuum suction to transport granular and powdery materials over distances and can automatically feed materials on time and in the right amount, reducing the cost of manual material feeding. It not only improves work efficiency but also reduces production costs.

the course of daily use, the material suction machine may encounter some faults or require maintenance. Today, let's discuss what to check and how to solve the problem when material suction machine does not suck or has insufficient suction.

Firstly, it is necessary to understand the working principle of the material suction machine, which uses a to create vacuum suction, forming negative pressure in the hopper cavity and sucking the material into the hopper. Therefore, when the material suction machine does not suck or has suction, it is possible to give priority to checking two aspects: blockage and vacuum negative pressure.

Firstly, regarding the blockage issue, it is possible to find the cause from the following 3 aspects.

1. Whether the feed inlet of the material suction machine is blocked by large pieces of material;

2. the filter element of the material suction machine is blocked. The pore size of the filter element will gradually be blocked with the service life, and it should be disassembled cleaned with ultrasound or replaced directly in time;

3. Whether there is a fault in the material suction machine's back-blowing system. The back-blow system is mainly responsible for cleaning the filter element. If there is a fault here, the service life of the filter element will be greatly reduced. This fault should replace the back-ing valve.

Secondly, regarding the vacuum negative pressure, it can be checked from the following 4 aspects:

1. Whether the pipeline connection is tight or.

2. Whether there is a fault with the electric motor

3. Whether the tightness of each valve of the material suction machine meets the requirements. For, whether the sealing ring is damaged, whether the electric air valve for discharge is leaking.

4. Whether the door plate can be closed tightly. The door plate must be closed to produce a vacuum pump. If there is material adhered to the material feeding door plate, it should be cleaned in time.
